Advanced shot
Instead of using the head of the club to line up your shot, it is much easier to use the shaft. Line up your players club with the "ghost" club to ensure a more fail-safe shot.
Building loyalty
Select Challenge mode and play a Vs. match to play. Press Start when the match begins and select the "Give Up" option. Repeat this three times to intentionally lose the match and increase the loyalty with that character.

Easy Loyalty
To gain easy loyalty with your characters, simply go to Challenge mode and find a VS match to play. Once you start, hit Start and choose the Give Up option. Do this three times and you will lose the match. There is no downside to this, but your loyalty with that character will go up.
